Alarm Systems

INTRODUCTION The Patton’s Medical gas alarm system monitors the status of the medical gas distribution system and provides audible and visual indicators. The master alarm can be furnished with Relay (BIM) building management system. The alarm can be used in conjunction with the Patton’s Medical optional Ethernet compatible system to monitor the status of all alarm and manifold systems on a PC. The Patton’s Medi-cal alarm system monitors the status of the medical gas sources in accordance with NFPA 99 and CSA Z7396.1. The Patton’s Medical gas alarm system is a two or three section assembly comprised of a rough-in box, a front panel and transducers (only if it is an area alarm or combination alarm). Rough-in Box The rough-in box houses the power supply, fuse, on/off switch, and a terminal strip for electrical wiring. An isolated transformer reduces the 110V or 220V AC input to low voltage DC. Front panel The front panel includes enclosed printed circuit boards with programming circuitry. The Push Button Module includes a power on indicator, programming buttons and an audible alarm. The Remote Signal Module(s) can monitor up to 16 signals per circuit board. Multiple remote signal modules can be ordered in a single alarm. The signals can be configured to display an abnormal condition on either a normally closed (NC) or a normally open (NO circuit. Each sig- nal may also be turned off it is not being utilized. The Remote Signal Module(s) with Relay (BIM module) are equipped with all of the above described features as standard Remote Signal module(s) described above. In addition, the r emote signal module(s) with Relay (BIM) are equipped with an extra set of remote signal dry contacts to interface with a building management system. The Gas (Area) module(s) on the front panel are identified with gas specific, color coded labels (per NFPA 99 or CSA Z7396.1). The gas displays include LED’s which indicate high/normal/ low pipeline pressure. A digital LED display shows the actual gas pressure. The gas pressure may be displayed in PSI and In Hg, or BAR or kPa. The unit is pre-programmed to display PSI / In Hg from the factory, but may be re-programmed in the field to display BAR of kPa. In addi- tion there are LED’s which illuminate to indicate System and Program failures. Each module is supplied with dry contacts for remote signaling of high and low pipeline pressure. Transducers The transducers converts pressure to an electrical signal and supplies the electrical signal to the alarm circuit board gas module panels. After the initial 24 hour 150 psi standing pressure test (required per NFPA 99) has been completed the pressure/vacuum transducers may be connected to the medical gas pipeline. The transducers may be remotely attached to the piping system at distances up to 5,000 feet using standard 18 gauge stranded twisted pair wire. Patton’s Medical recommends mounting the trans-ducers in the zone appropriate zone valve box or in the alarm back box. Should a transducer required service or replacement it is considerably more of a safety issue and more time consuming to locate and replace transducers which have been remotely located above the ceiling and eliminates contamination issues - such as having to set up a tent in order to remote ceiling tiles.

Alarm Installation

Installation of the Patton’s Medical alarm involves installing the rough-in box, the risers & the transduc-ers (if it is an area alarm or combination alarm) and front panel and making the necessary conduit, plumbing and electrical connections. All installation and testing should be done in accordance with NFPA 99 or CSA Z7396.1. WARNING: Electrical power intended for the alarm to be installed should be disconnected prior to in-stallation. WARNING: This device should only be installed by qualified personnel. Installation should not be at-tempted by anyone not having general experience with the installation of devices of this nature.

Rough-In Box Installation

(Side/end view of rough-in back box)

This is a rough-in box for a combination alarm. Your rough-in box should look the same or similar to this unit. The risers are shipped loose, for pro-tection during shipment, and must be installed. If transducers are to be mounted remotely, it is rec-ommended that they be connected to the DISS demand check valves installed in the correspond-ing zone valve box. Refer to the building plans to determine the loca-tion of the alarm. The contractor is to provide rigid mounting that will support the alarm box on both sides. The metal flanges provided on both sides of the rough-in box are to rest against the rigid mounting brackets. Screws (contractor provided) are to be driven thru the holes in the metal flanges into the mounting brackets. Flanges are adjustable to allow for a drywall depth of 1/2” to 1 1/8”. Mount alarm rough-in box so it will be flush or just below the finished wall surface using the ad-justment feature on the flanges. Recommended mounting height of alarms is generally 66” (generally accepted) from floor to top of fin-ished alarm unless specifically detailed otherwise.

Alarm Installation

Wiring

The power supply hole is located in the bottom (left side) of the rough-in box. Remove the plastic cover and panel covering the power supply. Remove the plug from the hole. Make conduit connections for wiring from the facility emergency power source.

To remove the power supply cover, loosen the two screws at the top of the cover and slide the cover to the right, then lift the cover over the screw heads. Slide the wiring harness strain relief to the left until it is free from the cover.

Route wires through the power supply conduit in-stalled in the bottom and left side of the rough-in box. Connect the 120 or 240 VAC facility emer-gency power source electrical wiring to the termi-nal strip provided on the lower left side of the box. (N = neutral, L = Line (hot), FG = field ground)

Use either of the two 1/2” conduit knock-outs pro-vided on the lower left side and bottom of the rough-in box to route conduit to supply either 120 or 240 VAC to the power supply. Note: Separate conduit should be used for low voltage wires (use knock outs provided on the top of the box).

Alarm Installation

Plumbing the Riser Extension Tubes

The wiring harness will be provided pre-wired to the power supply. If by chance you are replacing a wiring harness, the single green ground wire should be fastened to the screw on the top left corner of the power supply board. The wiring plug in con-nector (which should contain the rest of the wires), plugs into the connector terminal on the upper left corner of the power supply board. The black wire will be on the top.

This is how the power supply should look when the wiring is completed. Replace the power supply cover and plaster cover (to protect the unit while the drywall and wall cov-ering work are being done) after wiring is complete

Note: It is recommended that gas piping system tubing be connected from the extension tube to the ceiling for a future or blank gas display even though a transducer is not being installed. Cap the unused tube above the ceiling. This will simplify future expansion. Note: It is possible to install the transducers remotely (not in the alarm box). In this type of installation the risers are connected to the gas piping system up to 5,000 feet away from the alarm panel. Note: Patton’s Medical recommends mounting the transducers either in the zone valve box (remote) in or in the alarm back box - not remotely above the ceiling. Should a transducer require service or replacement it is considera-bly more time consuming to locate and replace or service transducers remotely located above the ceiling.

Install the risers in the top of the back box as shown. After removing the protective plastic caps, connect the riser ex-tensions tubes to the gas piping system per NFPA 99. Make sure the drop is for the proper gas service. Using a purge gas to insure cleanliness in the tubes, silver braze the joints. Do not use soft solder. Conduct heat away from the check valves. (A purge kit is required for purge equip-ment connection to the system). The 150 psi standing pres-sure test of the piping system must be successfully com-pleted and all pressure removed from the system before connecting the transducers to the system. Attaching transducers without depleting the 150 psi standing pressure first will result in damage to the transducers.

Installing the Hinges

Installing the Alarm Front Panel

After the walls are finished, the hinges may be in-stalled onto the rough-in box. The two hinges should be fastened to the lower front edge of the rough-in box using the screws provided. The hinge should rest flat against the surface of the drywall.

Slide the rectangular holes cut into the bottom edge of the front panel over the front catch of the hinges. Support the front panel in the open position to at-tach the lanyards.

Attach the two (left & right side) lanyard cables to the alarm front panel using the screws provided.

Wiring the Alarm Front Panel to the Power Supply

Installing the Transducers (non remote)

Attach the green ground wire, which is in the wir-ing harness, to the ground screw on the left corner of the front panel - just in front of the power sup-ply.

Attach the plug connector at the end of the wiring harness to the appropriate connector located at the top left corner of the button module circuit board. The plug should lock into place. The plug can only be inserted on way.

This is how the wiring harness plug connector should look when properly installed on the back of the button module board.

After depressurizing the 150 psig standing pressure from the piping system, install the appropriate transducers to the appropriate riser extension tube connectors inside the rough-in box. Hand tighten then torque lightly with a wrench.

12

Alarm Systems

Installing the Transducers (remote)

Transducer assemblies with DISS gas specific fit-tings have also been provided and, after the 24 hour standing pressure test is completed and normal oper-ating pressure has been restored to the medical gas piping system, they must be connected to the DISS demand valves. Note: maximum mounting distance of each remote transducer is 5,000 feet away from the alarm panel to which it will be wired. Follow the wiring instructions in Appendix F.

The transducers have been designed so that they may be installed in a standard 4”x 4”x 2 1/8” electri-cal junction box for added protection.

A panel mount feature has been provided to allow mounting of the transducer using standard 1/2” con-duit connections and 4”x 4”x 2 1/8” junction boxes. Note: The DISS nut & nipple will need to be re-moved to allow installation of the conduit nut and the re-installed using oxygen safe Teflon tape.

13

Alarm Systems

Connecting the Transducer Wiring to the Alarm Front Circuit Board

The wire terminal connector on the gas board has six wire connection slots. The two wires from the transducer should be installed in the BLK & WHT SENSOR slots. These are the two slots closest to the center of the gas board (as shown). It is pre-ferred that the black wire be closest to the center of the gas board.

The other four connection slots are for optional remote signals of the low and high line pressure alarms.

The transducer plug may be removed from the gas module to make it easier to install the wires.

Visually verify that the appropriate transducer wire pair has been attached to the appropriate gas mod-ule by looking at the front of the alarm panel. If there is not an Error Condition and a System alarm, the proper (matching gas service) transducer has been connected to the gas board.

14

Alarm Systems

Wiring the Remote Devices to the Remote Signal (Master) Board

Locate the two banks of 16 terminal connectors on the back of the remote signal (master) board.

There are a total of 32 connection points - two connection points for each remote signal. The pairs are la-beled 1 IN thru 16 IN on the circuit board. The NC (normally closed) labeled terminal of each pair is where the signal wire should be landed.

The connector terminal may be un-plugged from the circuit board - to simplify installation of the remote signal wires.

Land the corresponding common wire on the C (common) terminal of each pair of terminal connectors.

Labeling the Alarm Front

After all remote signal (master) wires have been landed, identified & cataloged (using appendix C in this manual), you are ready to apply the remote signal labels. Remove by unthreading the two ny-lon nuts shown here from the back of the alarm front panel.

The gas modules are shipped pre-labeled from the factory. If a gas service is changed to a different gas or added to the alarm, it will be necessary to insert the appropriate label in the pocket of the gas module. The new gas label supplied by Patton’s Medical will slide into the gas module label pocket of the gas module label.

The panel will now lift out of the white frame. Pro-vided in the packaging with the alarm front panel is a long white card and a pre-printed sheet of labels for the remote alarm signals. Wash your hands before handling these labels and cards! Apply the labels to the appropriate position on the card using the guide lines on the card. When complete, insert the card into the “Monitored Signals” label pocket of the “Monitored Signals” label.

A blank label has been provided at the bottom of each gas module for room identification. You may type directly onto this label or apply a pre-printed label. The label supplied by Patton’s Medical will slide into the gas module label pocket of the gas module label.

Alarm Installation

When the labeling is complete, install the plate into the white frame and re-attach with the two nylon nuts.

Check the green power LED indicator on the front of the button module. It should be illuminated.

You are now ready to supply power to the alarm. Restore power to the circuit feeding this alarm panel. The toggle switch on the front of the power supply should be placed in the ON position.

If you haven’t already, you are now ready to pressurize the piping system to normal operating pressures. The alarm is shown here with Oxygen & Medical Air at normal operating pressures. All remote signal points (master alarm signals) are shown in normal condition.

Alarm Displays & Functions

Gas Module (Area Alarms) Pressure Reading Display The LED Digital Pressure Display displays the pres-sure as indicated by the transducer. The gas pressure may be displayed in PSIG/In Hg, BAR or kPa. PSIG and In Hg is the factory setting. Note: Vacuum & EVAC/WAGD are actually dis-played as inches of Hg in the PSI mode. In kPa mode the Nitrogen gas display indicates one tenth of the actual pressure when the pressure exceeds 999 kPa (i.e. 1100 kPa is displayed as 110 and the kPa and (x 10) LED is lit). Note: Alarm settings are maintained even if power is interrupted. Units of Measure Indicator The Units of Measure Indicator illuminates PSIG/In Hg, BAR or kPa (whichever is selected during pro-gramming - PSIG and In Hg is a factory setting) pro-viding the unit of measure displayed on the LED pressure reading. In the kPa model the Nitrogen gas display indicates one tenth of the actual pressure when the pressure exceeds 999 kPa (i.e. 1100 kPa is displayed as 110 and the kPa and (x 10) LED is illu-minated). High / Normal / Low Status Lights Should the line pressure of a gas exceed the pro-grammed alarm set points for low or high line pres-sure LED will be illuminated simultaneously with the buzzer sounding to announce an alarm condition has occurred. When the line pressure is neither high nor low it is considered within the normal range and the green Normal LED is illuminated. These indications are relative to the high and low pressure set points which have been programmed into the alarm. These high and low set points should be set in accordance with NFPA 99 and CSA Z7396.1 at ± 20% of the nor-mal operating pressure. System LED The System LED illuminates in the event of a system problem or malfunction. The following codes will be displayed when a System Error or Failure is detected, or when the History button is pressed:

Code Error 0 No error (History only) 1 Flash EE corrupt, defaults 2 Sensor: open or broken line 3 Sensor: com timeout, data not received when expected 4 Sensor: Noise on line, or data errors 5 Sensor: Gas type/range mismatch Actual low psig Low pressure (history only) Actual high psig High pressure (history only)

Remote Signal Status LED’s (Master Module) Normal Status Light (Green) The normal green status light when illuminated signi-fies that the equipment being monitored is not in an alarm condition. Abnormal Status Light (Red) The abnormal status light when illuminated signifies that the equipment being monitored is in an alarm condition Note: If no LED is illuminated the remote signal status LED’s have probably been set in the disabled or off position. This can be verified by placing the Remote Signal circuit board in the programming mode and pressing the → to view the status of the remote signal point in question or by simply pressing the Test button to verify that the LED’s are func-tional. Program Mode When a circuit board is placed in the program mode (see Programming Modules - page 23) the board may be re-programmed. The brightness level of the circuit boards other than the one in the program mode is de-creased. In addition, on Gas Displays (Area Modules) the PGM (Program) LED is illuminated, on Remote Signal Displays (Master Modules) the first Remote Signal point will blink.

Alarm Operation

Master Alarm Panels Remote Signal (Master Module) With electrical power applied to the alarm, it will monitor the status of the medical gas distribution system and the remote equipment connected to it. The remote signals (master module displays (via LED indicators) the normal/abnormal status of the remote equipment connected to the alarm. All alarm panels are pre-programmed upon leaving the factory to monitor normally closed signals (per NFPA 99). In normal operation all active signals will be green. Whenever an abnormal status signal is detected the corresponding green LED will illu-minate. Simultaneously an audible alarm will sound. Pressing the Silence button silences the au-dible alarm (the Red LED continues to be lit). The appropriate personnel should be notified immedi-ately of the alarm condition. When the alarm condi-tion has been rectified the Red LED is automati-cally extinguished and the Green LED illuminates. Note: master alarm signals do not repeat - only area (gas) modules are equipped with the Repeater Delay feature. Silencing the Alarm Press the Silence button when the alarm is sound-ing and the alarm will be silenced. Testing the Alarm Pressing and holding the Test button initiates a self-test of the alarm. All LED’s and seven segment displays will illuminate for as long as the Test but-ton is depressed. In addition the buzzer will sound. If any LED or seven segment display does not illu-minate - it is faulty and the circuit board should be replaced. If the buzzer does not sound, it is faulty and the circuit board should be replaced.

Note: The alarms (both Area & Master) are pro-grammed to ignore transient signals that are less than 0.7 seconds in duration.

Area Alarm Panels Gas Modules With the electrical power applied to the alarm and the gas systems adequately pressurized, the follow-ing indicators are illuminated: 1) the Power On LED, 2) the pressure readings of the gas on each gas display, 3) the Normal LED (green) on each gas display. If the pressure of one of the gases drops below the programmed low limit setting, the following events take place simultaneously: 1) the Normal LED will be extinguished, 2) the Pressure Low LED (red) will illuminate, 3) an audible alarm will sound. If the pressure of one of the gases rises above the programmed high limit setting, the following events take place simultaneously: 1) the Normal LED will be extinguished, 2) the Pressure High LED (red) will illuminate, 3) an audible alarm will sound. Silencing the Alarm Press the Silence button when the alarm is sound-ing and the alarm will be silenced. The area alarm is equipped with a Repeater Delay feature which monitors only the Gas Module (area) alarms. The Repeater Delay has been factory pro-grammed to make the alarm re-sound every 10 (ten) minutes as long as the alarm condition exists. Note: Remote Signal (master) alarms are not moni-tored by the Repeater Delay.

This section deals with the daily operational aspects of the alarm panel. The Programming The Alarm sec-tion covers the procedures to follow in order to configure the alarm if the preprogrammed settings are not appropriate, a module is added or deleted or if the alarm is being incorporated into a T-Net system. After installation has been completed and the alarm has been properly configured, it is ready for operation.

Alarm Systems

Alarm Operation System Alarm The audible buzzer will sound, the System LED will illuminate and an Error Code “Err” will be displayed on the digital pressure display when a system failure oc-curs or the history button is depressed. The System LED and “Err” will illuminate and flash on and off and alternate with a number (per table below) being dis-played on the digital display. Note: If “Err” should be displayed on the Gas Pressure Display of any gas module, this indicates a problem. Some possible problems and corrective actions are: The transducer is not connected to the Gas Module. To correct, check the transducer connection to the back side of the Gas Module. A transducer for a different gas service has been con-nected to the Gas Module. To correct, check the trans-ducer and the Gas Module gas identification labels and make sure they match. If the above corrective actions do not correct the prob-lem, contact the factory for assistance. Code Error 0 No error (History only) 1 Flash EE corrupt,defaults loaded 2 Sensor: open or broken line 3 Sensor: Com timeout, data not received when expected 4 Sensor: Noise on line, or data errors 5 Sensor: Gas type/range mismatch Actual Low psig Low pressure (history only) Actual high psig High pressure (history only) PGM Notification The PGM (program mode) LED will flash off & on when a gas module circuit board is manually placed in the program mode. It is important to note that while a gas module is in the program mode, it is not monitoring the medical gas pipeline. See the “Programming the Alarm” section of this manual for instructions on pro-gramming the gas module.

Programming the Alarm

The alarm has been programmed at the factory prior to shipment. Programming of the alarm may be nec-essary if: A) the high or low pressure limits for a gas need to be modified B) if a future gas module is being put into service for an added gas service C) if a gas service is being deleted D) if a gas service is being changed E) if a remote signal alarm point needs to be re-configured F) if a remote signal module is being added in the place of a blank module G) if the alarm identification number needs to be changed H) you wish to change the repeater delay time I) you wish to change the units of measure J) the alarm panel is being set up on the T- NET system Note: Only authorized personnel should program the alarm! It is important to note that while the alarm is in the program mode, it is not monitoring the medi-cal gas system and alarm conditions will not trigger an alarm. Accessing the Alarm Program Mode To program the alarm, the circuit boards must be placed individually, one at a time in the program mode. To place a circuit board in the programming mode, the dip switch located on the back side of the circuit board to be re-programmed, must be changed from the “run” to the “pgm” position. After this is done, the gas module (area) board being reprogrammed will be brighter than the rest of the gas module (area) boards (when viewed from the front) and the yellow “PGM” LED indicator will be flashing to indicate that the alarm is in the program mode and the board which is illuminated more brightly and has the flashing “PGM” LED is ready to be repro-grammed. The remote signal (master) board being repro-grammed will have the top (first) signal point flashing and the programming display LED’s (at the bottom of the board) will illuminate displaying either an “O” (open circuit) or a “C” (closed circuit) or a “d” (disabled).

The programming buttons, located on the front of the alarm, upper left corner (see photo on page 22) may now be used to make the needed program changes. When you have successfully accessed the program mode, it is important to note that some of the buttons revert to their sub-functions: When programming a gas (area) module: The UP key ↑ is used to raise the pressure set point and / or to toggle upward thru the list of sub- options. The DOWN key ↓ is used to lower the pressure set point and / or to toggle downward thru the list of sub- options. The RIGHT key → is used to toggle (scroll) thru the list of major options. The LEFT key ← is used to SAVE the new program-ming options after they are selected. When programming a remote signal (master) module: The UP key ↑ is used to toggle between the choices of the green LED or the red LED or both the green & reds illuminated (disabled). The DOWN key ↓ is used to toggle between the choices of green LED or the red LED or both the green & reds illuminated (disabled). The RIGHT key → is used to toggle (scroll) down to the next remote signal point. The LEFT key ← is used to SAVE the new program-ming options after they are selected. Note: In order to perform any of the following pro-gramming features you must first set the alarm in the program mode. Programming the High & Low Gas Pres-sure set points Immediately upon entering a gas module (area) board in the program mode, the high line pressure set point major option is displayed. If the gas module being programmed is a typical 50 psig delivery pressure gas, the board has been pre-programmed at the fac-tory with the high line pressure set point at 60 psig, so the display should show the number 60. If you wish to raise or lower this setting, simply use the up ↑ or down ↓ keys to adjust the pressure setting.

Programming the Alarm

After the setting has been changed to the new desired setting, press the LEFT key ← (SAVE) to save the new setting. Note: if the SAVE ← LEFT key is not pressed after making the change to the programming and before pressing any other keys, the new setting will not be saved and the alarm will revert to the pre-viously saved setting(s). When the SAVE key ← is depressed, three horizontal dashes will appear in the display. Press the → key to move on to the low line pressure and repeat the above procedure. Note: The alarm is designed with a safety feature so that the high and low set points must be at least 0.5 (psig / in Hg), 0.05 (bar) or 5 (kPa) increments apart. The high set point will not be able to be set below the low set point and visa versa. Programming the Remote Signal (Master) Alarm Points While in the program mode, the top signal point LED will be blinking. At the bottom of the same remote signal board, the Programming Display LED set will display the contact state for the blinking signal point. “O” = open, “C” = closed and “d” = disabled. The contact point that is flashing is capable of being re-programmed. (Note: in compliance with NFPA 99, all contacts are programmed as closed contact equals a normal condition from the factory). If it is necessary to re-program a signal point; press the → key to view the next Remote Signal Alarm Point, when the de-sired Remote Signal (Master) point is flashing, use the ↑ or ↓ keys to alter the point to the desired status, after the desired change is achieved, press the ← to save the change. Note: Any contact point that has been disabled will have both the green (normal) and red (alarm) LED illuminated only when in the programming mode, to make it easy to identify them. In the normal mode of operation, both LED’s of a disabled signal point will not illuminate nor will this signal point trigger an alarm. Note: When an alarm condition occurs the audible buzzer sound simultaneously with the corresponding red LED illuminating and the green corresponding LED being extinguished. When the silence button is depressed, the audible buzzer is silenced and remains silenced until another alarm condition occurs. Master Alarm signals do not repeat.

Programming the Gas Alarm Repeater Delay After placing a gas board in the program mode, press → until “dLY” is displayed on the digital display of the gas module then let go of the → key. A number will be displayed on the digital display. This number is the setting (in minutes) of the repeater delay. Using the ↑ or ↓ keys, adjust the repeater delay to the de-sired length of time (0 - 240 minutes). (Note: the re-peater delay is preprogrammed from the factory at 10 minutes - per NFPA 99). To save the change and re-turn the alarm to the normal alarm mode, press the ← button, then change the dip switch back to the “run” setting. Note: this procedure must be repeated for all gas boards on the alarm panel. Note: master alarm signals do not repeat. Note: If a valve of 0 (zero) is programmed and saved for any board, the repeater is disabled. If left pro-grammed this way after 72 hours, the board(s) will automatically revert back to the preprogrammed fac-tory setting of 10 minutes. Programming the Units of Measure Displays While in the program mode, press the → button until “-U-” is displayed on the digital display of the gas module then let go of the → key. The letters “PSI” or “bAЃ” or “PA” will be displayed on the digital dis-play. This is the unit setting that the gas board is set to display. If you wish to alter the unit display, use the ↑ or ↓ keys to select the desired unit display, then press the ← SAVE key. Note: this procedure must be repeated for all gas boards on the alarm panel. Note: Vacuum & EVAC / WAGD Gas Modules will automatically display in in/Hg when PSI is selected. Note: The kPa and x10 LED’s will both illuminate on all high delivery pressure Gas Modules (i.e. - Nitro-gen and Instrument Air) when kPa is selected. Be-cause the Gas Pressure LED Display is only able to display three digits and high delivery pressures viewed in kPa are four digits, the Gas Pressure LED must be read as a four digit number by multiplying the displayed number by ten. I.E. - the Gas Pressure LED Display is displaying 125 in kPa. The pressure should be read as 1,250 kPa (125 x 10).

Programming the Alarm

Adjusting the Digital Line Pressure The digital line pressure may be adjusted slightly (per the chart below) by following the simple procedure below. This can be done by one person at the alarm panel - no need to open/adjust the transducers! 1. Put the gas module you want to adjust into the

PROGRAM MODE. 2. Using the TOGGLE → (right arrow) button go to

the CAL mode. 3. Use the UP ↑ ARROW button to increase the

pressure reading and the DOWN ↓ ARROW to decrease the pressure reading. The adjusted read-ing will be displayed as the changes are made.

4. Press the SAVE button ← (left arrow) to save the setting.

5. You can return to the original calibration setting by pressing CLEAR then press the SAVE button ← (left arrow) while at CAL in the PROGRAM MODE. This should be done if a transducer is ever replaced, as the reading offset will be ap-plied to the new transducer readings.

Range of adjustment VAC or EVAC / WAGD ± 0.5 In Hg 100 psig transducers ± 2.5 psig 250 psig transducers ± 6.0 psig Programming the Board Identification # Note: This feature is only used when the alarm is used in conjunction with a Patton’s Medical T-Net system. Note: Each gas and master (remote signal) circuit board must have a unique Identification Number - no two can share the same number. After placing a gas board in the program mode, press → until “Cld” is displayed on the digital display of the gas module then let go of the → key. A number will be displayed on the digital display. This number is the board identification # assigned to the circuit board. Using the ↑ or ↓ keys, select the desired board identification #. Use the ← SAVE button when you are finished. Note: Each gas and master (remote signal) circuit board must have a unique Identification Number - no two can share the same number.

Note: Valid identification numbers are 1 - 999. The alarm is pre-programmed at the factory with 0 (zero) as the zone identification number. Adding/Removing Modules or Changing the Gas Service of a Gas Board To remove either a gas board or a remote signal mas-ter board from an alarm - you simply need to turn off the power to the alarm panel (using the switch on the outside of the power supply in the back box), unplug the ribbon cable from the board being removed and then turn the power back on. The alarm will automati-cally reset itself. To add a remote signal master board to an alarm - you follow the same instructions above. Note: The following feature is only used if; an addi-tional gas service is being added to an area alarm, a future gas module is being set up for a new gas ser-vice or and existing gas module board is being changed to a different gas service. The gas boards are pre-programmed for a specific gas service from the factory. After placing a gas board in the program mode, it is possible to change the gas service of the board. The following list cross refer-ences the number that is actually displayed on the gas board numeric display with the full names of the gases:

T-Net ™ Interface, Circuit Board Installation

Patton’s Medical A1A/A1M series alarms may be ordered without T-Net Interface Cir-cuit boards. The T-Net Interface Circuit boards may be installed later.

You will be installing one of three types of interface circuit boards, bracket and cable connector; RS485, Ethernet or Wireless. The Ethernet Interface board is shown here left and the Wireless board is shown here right.

The toggle switch on the front of the power supply should be placed in the OFF position.

Note: Units incorporating the wireless interface circuit board - contains FCC ID OUR-9XTEND. The en-closed device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this device just accept any interference received, including interference that may cause undesired operation.

The cable must be installed into the socket on the Button Board properly - per the instructions of the cable.

All of the gas boards and remote sig-nal (master boards) will need to be re-programmed with a unique identifica-tion number and set up in the T-Net software per the T-Net installation instructions provided with the T-Net software.

The power may now be restored to the alarm. The alarm is fully functional - even if the T-Net software is not yet installed or is out of service.

Any of the three types installs into the bottom right corner of the alarm back box. The wire-less antenna drops thru a hole in the bottom of the back box.

The bracket mounts to the existing flange nut.

Building Management Interface, Relay (BIM) Board Wiring

Patton’s Medical A1A/A1M series alarms may be ordered with standard remote signal circuit board(s) or with the building management interface circuit board(s). The build-ing management interface circuit board(s) may be installed later, replacing the standard remote signal circuit board(s). It is only necessary to install building management inter-face board(s) in one of the master alarm panels.

The toggle switch on the front of the power supply should be placed in the OFF position.

Outlet connections - to building management system

Refer to Wiring Remote Devices to Remote Signal (Master) Board page 13 - the building management in-terface circuit boards (Relay boards) are wired the same way as the standard remote signal circuit boards. The additional two sets of connection terminal are the con-nection points for the wires outputting the signal infor-mation to the building management system.

Input connections - from remote signal devices

The connector terminals may be un-plugged from the circuit board - to simplify installation of the remote signal wires. There is no need to remove the wires, sim-ply unplug the connectors from the standard remote signal board and plug them back into the new building management interface circuit board. Be certain to match the label on the socket with the label on the plug.

The additional connector terminals are labeled 1 OUT thru 16 OUT are located on the left edge of the new building management interface circuit board. These correspond with the pairs labeled 1 IN thru 16 IN on the right edge of the circuit board. The NC labeled terminal of each pair is where the signal wire should be landed. The C labeled terminal of each pair is where the common wire should be landed.
